Combining Accelerometers with GPS to Investigate Children’s Outdoor Physical Activity

  • Added on June 16, 2011

Introduction With increasing interest in how the physical environment may influence physical activity, methods are needed that can be used to investigate the environmental context of activity. The aim of this study is to use combined accelerometer and GPS data to describe the level and location of children’s physical ...


Identification of Children's Activity Type with Accelerometer-Based Neural Networks

  • Added on June 16, 2011

Introduction Children’s physical activity has traditionally been measured with self-reports. Self-reports are easily administered, low-cost measurements. However, they do not capture the sporadic short-burst nature of children’s physical activity very well. Accelerometers have therefore, in recent times, become the method of choice in physical activity research. These devices ...



Measuring Total Sitting Time in Working Adults

  • Added on June 16, 2011

Introduction Much of the research about sitting measurement has focused on total sitting time [1] (Rosenberg et al) and leisure-time sedentary behaviours [2] (Clark et al 2009), with less attention given to other domains in which sitting and sedentary behaviours occur. This study aimed to assess the measurement properties of a measure of ...


Validity of Two Self-Report Measures of Sitting Time

  • Added on June 16, 2011

Introduction Evidence suggests that time spent in sedentary behaviours (usually defined as time spent sitting) is an independent risk factor for a number of adverse health outcomes [1] and there have been calls for the explicit measurement of sedentary behaviour in population surveillance studies [2]. To date, limited evidence exists on the ...


Using Observation to Compare Different Accelerometer Cut Points for Sedentary Behavior in Children

  • Added on June 16, 2011

Introduction Accurate objective methods for the assessment of sedentary behavior are crucial for population monitoring and evaluation of public health strategies for preventing childhood obesity. Actigraph accelerometers are a commonly used objective physical activity measurement tool. It is hypothesized that accelerometers may also provide a valid method for assessing children’...


Objectively Measured Sedentary and Physical Activity Behavior Across the Life Span

  • Added on June 16, 2011

Introduction Recent research shows that too much sitting has negative effects on health and well-being independently from people meeting the current physical activity (PA) recommendations [1]. However sedentary behavior (SB) is still an understudied topic. The aim of this study was to objectively investigate the time spent in sedentary and PA ...
